One of the rarest Topps test products ever issued, the Pocket Size Baseball game featured oversized, colorful cards that let you play the same scratch off game found in the 1970 and 1971 regular issue packs but with an entirely different look. The cards, which came two to a pack with a slab of bubble gum,  measure 5 1/4" x 3 1/8" and do not fold. No ballplayers were showcased, rather some period - and quite colorful - graphics were used. The back allowed for each "manager" to fill in his own roster. While undated, the graphics and size, which is the same as the 1970 and 1971 Supers, suggest the product was tested at the same time or possibly into 1972.  BBCE wrapped and very, very scarce, this is the only one we've ever seen.
